Grey
Heron in Flight (November 18, 2006)

| Canon EOS 20D, Canon EF 600mm f/4 L IS USM, 1/2000 f/4, iso 400, tripod. Torrile, Italy. |
Every time that I led a workshop about
birds and wildlife I teach to photograph in every weather condition:
sun, rain, fog or snow. Yesterday, the sky was quite cloudy and
sometimes there was a light rain...moreover, there was
even some fog, that remained for the entire day. Overall, the
conditions were far from great, but even in these situations you can
come back from the field with great photos.
When I've taken these photos there was
still some fog, but the light was enough to get a fast shutter speed
at ISO 400 f/4. Of course, the photo was pretty flat and
"grey" - the tele lenses exacerbates the effects of fog
and mist, but the subject still showed enough detail, so the photo
could be recovered with good post-processing techniques.
When I opened the RAW file, the photo
was like that:
|

|
| RAW
file, just converted and resized, without any adjustment
of contrast, sharpness, ect. |
The real scene was not that bad, from
what I remember it was something between this image and the
processed photo. Remember that I converted the RAW with my usual
approach of avoiding any enhancement of contrast, saturation or
sharpness (as explained in the article Introduction
to Adobe Photoshop) to get a untouched file with a low contrast
but the maximum amount of detail, that I process exclusively with
Photoshop...the tools of PS are far more advanced than those of
Camera RAW.
As you can see, the head is in the
center of the image...even though here I used AFPS (Automatic Focus
Point Selection), keeping the subject in the center of the frame
helps the AF; remember that when you select AFPS, the camera begins
by using only the center AF area then, when the center area has
focussed on the subject, the camera activates all the other AF areas
to follow the subject identified by the center area.
Even though the difference between the
RAW file and the processed photo is pretty noticeable, in this case
the post-processing was relatively simple. I cropped the photo to
improve the composition and I enhanced the contrast by dragging the
black and the white sliders towards the edges of the histogram (with
the Levels Tool of PS CS2), then I warmed up the colors to remove
the slightl blue cast and I increased the saturation on +20. I
removed the noise from background and subject with the Noise
Reduction of PS CS2. Photoshop is a great help to recover the
photos, but it can't do magic: you can recover contrast, color and
saturation, but there must already be some color and contrast in the
original photo. Moreover, you can not recover the sharpness: it is
essential to use a sharp lens and perfect focus techniques to get
razor sharp photos in-camera. The Smart Sharpen of CS2 helps to
improve the detail of the photos that are already quite sharp, if
the photo is out of focus the sharpening is useless.
This is another photo of the same
sequence:

The burst of 5FPS of the Canon EOS 20D
is a great help for wildlife photography. This photo is taken a
fraction of second after the previous photo, but the bird had
already moved some meters closer to the camera and it had a
completely different wing position.
